The TDS Sensor Kit is designed to measure the Total Dissolved Solids (TDS) level in water, helping you assess water cleanliness and quality. Fully compatible with Arduino and other 3.3V/5V microcontrollers, this kit enables real-time monitoring and easy integration into automation systems. It is ideal for domestic water systems, hydroponics, aquaculture, environmental monitoring, and educational projects. What is TDS? TDS (Total Dissolved Solids) represents the total concentration of dissolved substances in water, measured in parts per million (ppm). Higher TDS → More dissolved impurities Lower TDS → Cleaner water TDS measurement is commonly used as a quick reference indicator of water quality. Why Choose This Kit? Handheld TDS meters are affordable but cannot transmit data for logging or automation. Professional laboratory instruments offer advanced features but are often expensive. This Analog TDS Sensor Kit provides a balanced solution: Arduino-compatible for easy system integration Real-time analog output for monitoring and data collection Plug-and-play design with no soldering required Cost-effective for DIY and embedded applications Key Features Wide Input Voltage: 3.3V – 5.5V Analog Output: 0 – 2.3V (compatible with 3.3V and 5V controllers) AC Excitation Source: Prevents probe polarization, improving accuracy and lifespan Waterproof Probe: Suitable for continuous water immersion Measurement Range: 0 – 1000 ppm Low Power Consumption: 3 – 6mA working current Specifications Signal Transmitter Board Input Voltage: 3.3 – 5.5V Output Voltage: 0 – 2.3V Working Current: 3 – 6mA Measurement Range: 0 – 1000 ppm Accuracy: ±10% F.S. (at 25°C) Module Size: 42mm × 32mm Module Interface: PH2.0-3P Electrode Interface: XH2.54-2P TDS Probe Number of Needles: 2 Total Length: 83cm Interface: XH2.54-2P Color: Black Waterproof for long-term immersion Applications Water purification and filtration systems Hydroponic farming Aquariums and aquaculture Environmental monitoring Science experiments and educational projects Package Includes 1 × Waterproof TDS Sensor Probe 1 × Signal Transmitter Board 1 × Set of Connecting Cables Important Notes Do not use in water temperatures above 55°C. Keep the probe away from container walls for accurate readings. Only the probe and its cable are waterproof. The connector and signal transmitter board must be kept dry. This TDS Sensor Kit offers a practical and affordable solution for accurate water quality monitoring and seamless integration into microcontroller-based systems.
